These goggles are made out of real metal, rather than plastic as with most steampunk goggles available on the market today. In addition they feature a high quality strap with a metal buckle and leather-like material. Lenses are standard removable 50mm in diameter and clear. Add on some colored lenses for an even more spectacular look! As seen worn by Camren Bicondova on Fox’s new hit series, Gotham. Be sure to get a pair of green lenses to match! Wouldn’t these make a great costume addition for Halloween?!
